HTC ThunderBolt 2750mAh extended battery
Reviewed by Phil Nickinson
When it comes to extended batteries, there are a couple things I worry about. First and foremost is having more juice. That's a given, though. With the 2750mAh extended battery for the HTC ThunderBolt, you're getting nearly double the miliAmp/hours of the stock 1400mAh battery. So it's going to last longer. (Or in the case of the ThunderBolt on LTE, which sucks through a battery, you might actually get a day's use out of it.)

As for the size, it's definitely larger, sticking out from the back of the ThunderBolt, whereas the stock battery and cover are flush. That's to be expected, of course. Funny thing is, it doesn't feel too bad in the hand. It's noticeably heavier -- about 1 ounce -- but, again, that's to be expected. But our fingers rest comfortably on the top lip. So despite the added size and weight, it's not horrible.

Star Star Star Star Star htc thunderbolt extended battery
User: Randy L, Feb 2, 2012
Pros: extra battery life
Cons: none
I say that by far this is a great battery to use and have but im upgrading my MaH battery to a longer lasting MaH one. Im currently using 2750, i will be impressed when i get the 3200 MaH one.

Since getting my thunderbolt on week one the biggest draw back was battery life. Now I go a full 24 hrs without turning anything off. I can finally use it as it was ment to be used. this is a must have fort any thunder bolt user. If you have a thunderbolt you must get this battery.

User: Tanya M, Jun 8, 2011
Pros: Can easily get over 24 hours with this battery.
Cons: none
This battery far out-lasts the stock battery. I even used an app killer, disabled GPS and WiFi, etc., and my stock battery just didnt last past 5:30 PM (after unplugging from charging source at 7 AM.) Ive noticed this battery is still over half charged the next morning even though it wasnt plugged in throughout the night. Its not too bulky at all. However, you will need to get a different rubber/silicone/whatever cover for it.
Star Star Star Star Star An Absolute neccessity!!!
User: Seth V, May 31, 2011
Pros: You can Get a full day out your Phone :)
Cons: Makes the phone somewhat heavy and bulky, but you get used to it..
Before I got this battery, I had to carry a charger with me everywhere. My phone would only last around 6 hrs before it needed charging :( Now that I got this battery, I cant imaging NOT having it.. It has saved me :) I easily get a full day out of this battery with moderate to heavy use (FLASH on the other hand will kill any battery very quickly). I recommend this battery to everyone with a ThunderBolt !!! absolute MUST have accessory.
